What test should I use for this problem? 5. A graduate student in Health and Human Performance is interested in the effects of stress on reaction timeafter watching several near-accidents involving vehicles and pedestrians around campus in the weeks leading upto finals. He sets up a study where he randomly assigns 18 participants to one of three groups (high stress,moderate stress, and low stress; 6 individuals per group) based on their responses to a questionnaire thatcategorizes the overall responses of individuals as high stress, moderate stress, and low stress. The subjects arethen submitted to a reaction test in a driving simulator and the number of "accidents" and “near misses" arerecorded (see data below).When reviewing the literature on this subject, the graduate student finds three competing hypotheses."Hypothesis A" suggests that subjects under a moderate amount of stress will perform better than subjects ineither the very low or the very high stress groups. "Hypothesis B" predicts that subjects in the high stress groupwill perform better than subjects in either the low stress or the moderate stress groups. "Hypothesis C" predictsthat subjects in the moderate stress condition will perform more poorly than subjects in the low stress condition.High Stress6Moderate StressLow Stress81071011411857121331112

The table below shows the marks out of 40 for nine students on two tests. The tests cover similar content but on one test the students are allowed to use a calculator while on the other test calculators are not allowed. Student A B Calculator allowed (x) 8 10 Non-calculator (y) 12 14 (b) C 14 6 Student J scored 25 on the test with calculators allowed, but missed the non-calculator test. Use the marks for students A to I to find the value of the Pearson correlation coefficient between the marks x on the test with calculator allowed and the marks y on the non-calculator test, and the equation of the least squares regression line of y on x.

Describe the strength of the correlation between the marks on the two tests and explain how this may affect the accuracy of your estimate.
You’ll want to use nCr or nPr on your calculator for these first three problems. They are very time- consuming to compute by hand. Remember to use nPr when the order matters and nCr when it does not. You will find both commands by pressing the [MATH] key on your calculator and scrolling over to PROB. The factorial (!) is in this list as well.

ALREADY HAVE FIRST THREE ANSWERS NEED THE REST. ANOVA. Dr. Milgram is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results. Group 1) “Like a lot” Mean: 8 SS: 2 N: df: Group 2) “Like somewhat” Mean: 5 SS: 6 N: df: Group 3) “Dislike a lot” Mean: 2 SS: 4 N: df: Grand Mean: 4 df Within-Group: 9 df Between-Groups: 2 Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22)…

This is the question im stuggling with To study peanut allergies in children, 320 babies who were at high risk for developing peanut allergies were given peanuts. 3.2% of these babies developed peanut allergies. How many babies in the study developed peanut allergies? This is what i did: i cross multiply x with 100 and 3.2 with 320 then divided both sides by 100 to get x=10.24. I dont think its right because to me it doesnt make any sense my question is where did i go wrong? How many babies did not develop peanut allergies?

Solve the problem using H-test. Please show the complete detailed solution. The following are the achievement test scores for four (4) different groups of students, each group were taught by using different teaching techniques. Test the hypothesis of difference between techniques and their effectiveness. Complete the table.
